Description

COleDropTarget::OnDragEnter

Called when the cursor first enters the window.

COleDropTarget::OnDragLeave

Called when the cursor is dragged out of the window.

COleDropTarget::OnDragOver

Called repeatedly when the cursor is dragged over the window.

COleDropTarget::OnDragScroll

Called to determine whether the cursor is dragged into the scroll region of the window.

COleDropTarget::OnDrop

Called when data is dropped into the window, default handler.

COleDropTarget::OnDropEx

Called when data is dropped into the window, initial handler.

COleDropTarget::Register

Creating an object of this class allows a window to accept data through the OLE drag-and-drop mechanism.

To get a window to accept drop commands, you should first create an object of the COleDropTarget class, and then call the Register function with a pointer to the desired CWnd object as the only parameter.

For more information on drag-and-drop operations using OLE, see the article Drag and Drop (OLE).
